You don't need to cancel anything and you don't need 500k in the bank to use your DTV again.
*500k is only for application, not for every entry.*
Once DTV is issued, no embassy or border checks your bank balance again on re-entry - that check is done. I have not seen any case where BKK/DMK asked a returning DTV holder for bank proof after 1 year away. They just scan passport, see valid DTV till
*********
, stamp 180 days.
*Can you enter on tourist exemption instead to avoid using DTV?*
Technically no choice at border - if you have a valid DTV in system, immigration will use it automatically. You can't say "please give me 60 day tourist instead of my 5 year DTV". The system defaults to your long-term visa.
But that's actually better for you:
- DTV stamp = 180 days, no extension needed for 4 week trip
- Tourist exemption = 60 days max from Sept 2025
- No TM30 or extra hassle for DTV, just same as tourist
*You only have a problem if:*
- DTV is revoked - which doesn't happen for low bank balance
- You overstayed last time - then you might get pulled
So just fly in with DTV eVisa PDF on phone, do TDAC, enter. No need to show any bank statement.
If you really want to enter as pure tourist, you'd need to formally cancel DTV at Thai embassy before travel - which makes zero sense for a 4 week trip.
Your DTV is still your best ticket even for short visit.
You could consider reading a book or two before your trip. I’d recommend Unlock Thailand by Isla Rey on Amazon, it includes all the info and insights you need. You should check it out. A very good companion 👌.
